TROLLEY-WIREHANGER.

SIECIFICATION forming part of Letters Patent N 0. 679,953, dated August 6, 1901.

Application filed December 20, 1900. Serial No. 40,557. (No model.)

To aZZ whom, it may concern;

Be it known that I, ALBERT D. CROSSLEY, a citizen of the United States, residing at South Norwalk, county of Fairfield, State of Connecticut, have invented a new and useful 'lrolley-VVire Hanger, of which the following is a specification.

My invention has for its object to provide a trolley-wire hanger that will do away with all soldering of the wire, will bend the wire but slightly, and will provide a smooth surface practically continuous with the wire for the trolley to travel upon, the bearing-surface of the hanger being relatively long and am ply thick to stand the requirements of use for practically an unlimited length of time and the hanger proper consisting of but two members, both of which shall be relatively light and both of which may be cast to the required shape and will need practically no finishing whatever, thereby insuring the maximum of efficiency and durability at a minimum cost.

With these ends in view I have devised the simple and novel trolley-wire hanger of which the following description, in connection with the accompanying drawings, is a specification, reference characters being used to designate the several parts.

Figure 1 is an elevation of my novel trolley-wire hanger, the lower member being partly broken away; Fig. 2, a plan view, the threaded shank of the insulator being in section on the line 2 2 in Fig. 1; Fig. 3, an elevation of the upper member detached, and Fig. 4 is a transverse section on the line 4 4 in Fig. 1.

A denotes the insulator, which is shown as provided with a threaded shank 10. It should be understood that the insulator forms no portion of my present invcn'tionfmy novel hanger being adapted for use in connection with any of the ordinary insulators now upon the market.

B denotes one member of my novel hanger, which for convenience I will term the lowermember, and C the other member, which for convenience I will term the upper member. Member B comprises an elongated trough 11, which is adapted to receive the trolley-wire D, the bottom of the trough being made thickest at its mid-length, as at 12,

ing the wire tightly to the hanger.

, hub.

so as to provide an amount of metal for wearing purposes amply suflicient to withstand long-continued usage. From the thick portion 12 at the center of the trough the metal diminishes in thickness with a slow taper toward both ends, so that the thick portion of the bottom is but slightly higher than any other portion, thus requiring but a slight bend of the trolley-wire, and the under side of the hanger is but slightly lowest at the center, so that the trolley will pass on and off the hanger easily and without appreciable shock at either end thereof. At the top ofmember B isaslotted hub 13, which is internally threaded to receive the threaded shank 10 of the insulator, the split or slot through the hub, which I have indicated by 14, being continuous with the trough, so as to permit the trolley-wire to pass into the trough.

Member 0 comprises a clamping-piece 15, which is adapted to just pass through slot 14. and into the trough, and a ring 16, which just passes over the hub, as clearly shown in the drawings. The lower side of the clampingpiece is curved longitudinally (see Fig. 3) to correspond'with the curvature of the bottom of the trough and is provided with a longitudinal groove 17, whose transverse curvature is the reverse of the transverse curvature of the bottom of the trough, so that a trolleywire will be gripped firmly between the two curved surfaces. The top of the ring is made slightly higher than the top of the hub, as clearly shown in Fig. 3, so that when the threaded shank of the insulator is turned down' to place in the hub the insulator will engage the top of the ring, as clearly shown in Fig. 4, and when the insulator is tightened the clamping-piece, which is made integral with the ring, will be forced down upon a trolley-wire lying in the trough, thereby lock- In order to strengthen the connection of the ring to the clamping-piece, lugs 18 may be cast uponthe inner side of the ring, which in .the assembled position will engage the slot in the This, however, is a mere detail of construction that does not go to the merits of the invention. In order to insure that member B cannot possibly become separated from member C, even should the latter by any posclamping-piece of member 0 in the trough over the wire,.the ring on member 0 passing over the hub on member B. The threaded shank of the insulator is then turned down to place in the hub, the under side of the insulator engaging the top of the ring and forcing the clamping-piece down upon the trolley-Wire, which is thus securely gripped between'the clamping-piece and the bottom of the trough.

Having thus describedmy invention, I

. claim-- 1. A trolle '-wire hanger consisting of members B and C, said memberB comprising an elongated trough of rigid unyielding material havinga bot-tom made thickest at its midlength and integral with the sides and diminishing in thickness toward both ends and a hub having a slot continuous with the trough, said slot having a permanent width sufficient to receive the trolley-wire, and said member 0 comprising a clamping-piece adapted to pass within the trough and a ring adapted to pass outside the hub, the lower side of said clamping-piece being curved longitudinally to correspond with the curvature of the bottom of the trough and having a longitudinal groove to receive a trolley-wire which is securely locked between the trough and the clamping-piece.

2. A trolley-wire hanger consisting of members B and C, said memberB comprising anelongated trough of rigid unyielding material having a bottom made thickest at its midlength and integral with the sides and diminishing in thickness toward both ends and a hubhavinga slot continuous with the trough, said slot having a permanent width sufficient to receive the trolley-wire, and said member 0 comprising a clamping-piece adapted to pass within the trough and a ring adapted to pass outside the hub, the lower side of said clamping-piece being curved longitudinally to correspond with the curvature of the bottom of the trough and having a longitudinal groove to receive a trolley-wire and said ring standing higher than the 'hub so that when either of saidmembers is held and the other member moved toward it the trolley-wire will be clamped between said members.

3. Atrolley-wire hanger-consisting of members B and 0, said member B comprising an elongated trough of rigid unyielding material having a bottom made thickest at its-midlength and integral with the sides and diminishing in thickness toward both ends and a hub having a slot continuous with the trough, said slot having a permanent width ,sufficient to receive the trolley-wire, and an internal screw-thread adapted to engage the shank of an insulator, and said member 0 comprising a clamping-piece adapted to pass within the trough and a ring adapted to pass outside the hub and to be engaged by an insulator when the shank of the latter is turned down to place in the hub so that a trolley-wire will be locked between the c1ampingpiece and the bottom of the trough.

at. A trolley-wire hanger consisting of members B and C, said member B comprising an elongated trough havinga bottom made thick estatits mid-length and diminishing in thickness toward both ends and a hub having a slot continuous with the trough and recesses 20, and member 0 comprising a clampingpiece adapted to' pass within the trough and a ring adapted to pass outside the hub and having lugs adapted to be turned into the recesses, whereby the members may be locked together in use independently of the insulator.

5. The combination with member Bliaving a trough of rigid unyielding material with integral sides and bottom to receive'a trolley-wire and a hub having a slot continuous.

with the trough and an internal screw-thread adapted to engage an insulator-shank, said slot having a permanent Width sufficient to receive the trolley-wire, of a member 0 having a clampingpiece adapted to pass within the trough and a ring which passes outside the hub and stands higher than the hub so that'when the shank of an insulator is turned down in the hub the insulator will engage the.

ring but not the hub, substantially as described.

6. Atrolley-wire hanger consisting of members B and C, said member B comprising an elongated trough of rigid unyielding material having a bottom made thickest at its midlength and integral with the sides and diminishing in thickness toward both ends and a hub having a slot continuous with the trough, said slot having a permanent width sufficient to receive the trolley-wire, and said member 0 comprising a clamping-piece adapted to pass within the trough and a ring adapted to pass outside the hub and to be engaged by an insulator when assembled, as described.

In testimony whereof I affix my signature in .presence of two witnesses.

ALBERT D. OROSSLEY.
